Creeper Joints are also available in a shackle mount for use with leaf
springs. Using a Creeper Joint on the shackle end of a leaf spring
reduces spring binding and increases suspension flex. Creeper Joint
shackle mounts are sold in pairs and do not include the shackles, bolts
or spring bushings. Three different flex ball sizes; 9/16" 5/8" &
18mm, allow you to choose the right size to match your application.
Toyota Pickup & 4Runner use 18mm size.
